Automated manual transmission for vehicle

Abstract

An automated manual transmission apparatus for a vehicle, may include a shifting unit having a plurality of stages between an input shaft and an output shaft and selectively cutting power to the input shaft and the output shaft when shifting between the stages, and a continuous transmission mechanism that may be disposed between the output shaft and a power supply that supplies the power to the input shaft of the shifting unit, wherein the continuous transmission mechanism selectively transmits the power from the power supply to the output shaft with a continuous transmission gear ratio.

What is claimed is: 
     
       1. An automated manual transmission apparatus for a vehicle, comprising:
 a shifting unit having a plurality of stages between an input shaft and an output shaft and selectively cutting power to the input shaft and the output shaft when shifting between the stages; and 
 a continuous transmission mechanism that is disposed between the output shaft and a power supply that supplies the power to the input shaft of the shifting unit, wherein the continuous transmission mechanism selectively transmits the power from the power supply to the output shaft with a continuous transmission gear ratio, 
 wherein the continuous transmission mechanism includes:
 a driving conical body that forms a conical surface and is connected to the power supply; 
 a driven conical body that forms a conical surface opposite the conical surface of the driving conical body at a predetermined distance therebetween; and 
 a movable roller disposed between the two conical surfaces of the driving conical body and the driven conical body and movable between the two conical surfaces so as to change a position thereof between the two conical surfaces and to transmit a rotational force of the driving conical body to the driven conical body with the continuous transmission gear ratio, 
 
 wherein a clutch that selectively transmits the power from the power supply to the input shaft is disposed between the input shaft and the power supply, and 
 wherein the clutch has a clutch disc disposed inside the driving conical body to control the power from the power supply. 
 
     
     
       2. The automated manual transmission apparatus of  claim 1 , wherein a rotation axis of the driven conical body is in parallel with a rotation axis of the driving conical body. 
     
     
       3. The automated manual transmission apparatus of  claim 1 , wherein a power control mechanism is disposed between the driven conical body and the output shaft to connect or cut the power therebetween. 
     
     
       4. The automated manual transmission apparatus of  claim 3 , further including:
 a driving gear; and 
 a driven gear engaged with the driving gear and connected to the output shaft, 
 wherein the power control mechanism selectively couples the driven conical body to the driving gear to connect or cut the power between the driven conical body and the driving gear. 
 
     
     
       5. The automated manual transmission apparatus of  claim 1 , further including:
 a control motor; and 
 a feed rod, wherein an end of the feed rod is connected to the control motor and the movable roller is rotatably connected to the other end of the feed rod, 
 wherein the control motor controls a longitudinal straight motion of the feed rod to move the movable roller between the two opposite conical surfaces of the driving conical body and the driven conical body. 
 
     
     
       6. The automated manual transmission apparatus of  claim 1 , wherein a shifting mechanism of the shifting unit is implemented by a synchro-mesh mechanism in which the shifting mechanism is engaged after synchronization by using a key and a synchronizer ring. 
     
     
       7. The automated manual transmission apparatus of  claim 1 , wherein a shifting mechanism of the shifting unit is implemented by a dog clutch. 
     
     
       8. The automated manual transmission apparatus of  claim 1 , wherein a rear idle gear is disposed between the input shaft and the output shaft.
